What if the cure for asthma was more than a miracle - what if it was a message?In a near-future UK, Verdance Pharmaceuticals stumbles onto a revolutionary compound: an inhaled therapy that almost eliminates asthma. Hospitals empty, deaths plummet, and billions flood into the company's coffers. The drug, VX-311, is hailed as the medical breakthrough of the century - until the unthinkable happens.Years later, autopsies reveal something terrifying: the lungs of patients are evolving. Gills. Cartilage. Aquatic traits not seen for millions of years. As humanity grapples with a biological metamorphosis no one understands, a young American researcher proposes a shocking idea - maybe the ocean isn't killing us. Maybe it's calling us home.Soon, a hidden underwater city in Scandinavia reports miraculous recoveries under experimental aquatic therapy. The phenomenon is dubbed The Atlantis Effect. What begins as a medical anomaly becomes a global shift: families divided between land and sea, a planet healing, and a species redefined.At the centre of it all is Dr. Imogen Sharpe, a scientist who journeys beyond the oceans - and the stars - to uncover a truth that rewrites evolution itself. Because VX-311 was never just a drug. It was a signal. And Earth was never alone.
